Based on our own years of practical experience, numerous expert knowledge and mathematics-based theory, we believe that an Expert Advisor suitable for practice must have the following requirements: long-term profitability, exclusion of risky techniques and use of Stop Loss.
Expert Advisors that do not have these criteria may very well be successful in terms of profitability, but the factor of uncertainty is much greater. That is, even if the backtest shows good results, the predictability and confidence is much more limited.
